The Cooing: FM & Drone Architecture Pigeon cooing consists of pure sine waves modulated by an organic LFO envelope. Amplified above 100 dB, it ceases to be a bird; it transforms into a massive, low-mid frequency drone that tests physical spatial thresholds. When a flock coos simultaneously, minor pitch offsets trigger phasing (acoustic beating)—the foundational micro-structural phenomenon of minimalism.
The Flapping: Micro-Glitch & Impulse Trains The wing flap is a pure glitch—a sequence of discrete acoustic impulses and non-periodic attacks. At extreme volumes, this erratic impulse train acts as high-energy envelope modulation, resembling concentrated white noise bursts. Isolating its razor-sharp transient response yields pointillistic, staccato percussion for a granular synthesis matrix.
Urban Space: The Brutalist Synthesizer Concrete, glass, and architectural voids form a macro delay matrix that reflects these waves. The city itself becomes a giant synthesizer, physically driven by the avian population acting as biological oscillators. This reductionism exposes raw acoustic materiality, expanding our paradigm of spatial texture.
